My invention relates to tobacco smoking pipes.

An important object of the invention is to provide a pipe which willproduce a cool smoke.

A further object of the invention is to provide 1'. a pipe having meansfor withdrawing the smoke at a point spaced from the bottom of the bowlof the pipe, whereby certain impurities will remain in the bottomportion of the bowl.

A further object of the invention is to provide it means fordistributing the suction action of the pipe around the periphery of thebowl.

A further object of the invention is to provide means whereby any numberof upper bowl-sections may be used in connection with the lower Itbowl-section, thus enabling the user to have a number of pipes differingin appearance.

A further object of the invention is to provide means whereby differentstems may be used in connection with the bowl.

251 Other objects and advantages of the invention will be apparentduring the course of the following description.

In the accompanying drawing forming a part of this application and inwhich like numerals are 2.5 employed to designate like parts throughoutthe same:

Figure l is a perspective view of the tobacco smoking pipe embodying myinvention,

Figure 2 is a central vertical longitudinal sec- 30 tion through thesame,

Figure 3 is a horizontal section taken on line 3--3 of Figure 2,

Figure 4 is an exploded perspective view of the pipe, parts broken away,and,

35 Figure 5 to 8 inclusive are side elevations of upper bowl sections ofdifferent shapes.

In the drawing, wherein for the purpose of illustration are shownpreferred embodiments of my invention, the numeral I ll designates thebowl ,0 of the pipe, as a whole, comprising an upper bowlsection I I anda lower bowl-section I2. The upper bowl-section II is considerablylonger than the lower bowl-section I2. Preferably formed integral withthe lower bowl-section I2 is a stem sec- 45 tion I3, as shown. I

The bore of the upper bowl-section H is preferably counterbored, asshown at I4, for receiving a cylindrical sleeve I5, which may be formedof metal or the like, and held within the counter- 50 bore by a frictionfit or by any other suitable means. The sleeve I5 is open at itsopposite ends and the lower portion of the sleeve is screwthreaded, asshown at I5, to engage with screwthreads I7, formed in the side of thebore I8 oi 55 the lower bowl-section I2. It is thus seen that the sleeveI5 serves as means to detachably conmeet the upper bowl-section II withthe lower bowl-section I2, these bowl sections contacting at I9, to forman air-tight fit. The sleeve I5 is provided with a horizontal annularset of apertures 5 preferably punched outwardly, and this annular set ofapertures is arranged at a point generally equi-distantly spaced fromthe opposite ends of the sleeve I5. At its lower end, the upperbowlsection I I is provided at its lower end with an in- 10 ternalannular cut-away portion forming an internal frusto-conical wall 2|. Thelower bowlsection I2 is provided at its upper end with an internalannular cut-away portion providing an internal frusto-conical wall 22.The frusto-conical walls 2| and 22 register, providing an internalannular chamber, which increases in width inwardly toward the sleeve I5.This sleeve I5 extends across the inner open end of the annular chamber23 and the annular set of outwardly stamped apertures 20 lead into theannular chamber 23, the free ends of the apertures being spaced from thefrusto-conical walls 2| and 22, as shown. The sleeve I5 extending acrossthe inner open side of the annular chamber 23 pre- 25 vents the tobaccofrom entering this annular chamber, while the apertures 2!] permit ofthe passage of the smoke. The sleeve I5 also serves to detachablyconnect the upper and lower bowlsections Ii and I2. Whenthebowl-sections II and I2 are separated, the sleeve I5 may be removedfrom the upper bowl-section and the frusto-conical walls 2i and 22 maybe readily cleaned or wiped off.

The stem section I3 is provided with a port or passage 24, which isforked at its forward end, providing passages 25, leading into theannular groove 22. The stem section I3 has a screwthreaded recess 26,formed in its end to receive a screw-threaded extension 27, carried by astem section 28, having a bore 29, in communication with the bore 25.The stem section 28 has the usual bite 38. It is obvious that the stemsection 28 is detachably secured to the stem section I3 and that stemsections of dilierent shapes and lengths may be secured to the stemsection I3, when desired.

In Figure 4, I have shown an upper bowl-section Ila, which is circularin cross-section and tapers downwardly. This bowl-section has the sleeveI5 and associated elements and is otherwise identical with thebowl-section II. In Figure 6, I have shown a bowl-section II b whichtapers upwardly and downwardly and is circular in cross-section. Thebowl-section N19 has the same sleeve l and associated elements and isotherwise identical with the bowl-section II. In Figure 7, I have showna bowl-section llc having a wider intermediate portion 3| and oppositelytapering end portions 32 and provided with the sleeve Hi. Thisbowl-section is otherwise identical with the bowl-section H. In Figure8, I have shown a bowl-section lld, having an intermediate cylindricalportion 33 and oppositely tapering portions 34 and the sleeve l5. Thisbowlsection lid is otherwise identical with the bowlsection ll. Thebowl-section H may be removed from the bowl-section l2 and any one ofthe upper bowl-sections shown in Figures 5, 6, '7 and S, substitutedtherefor.

It is to be understood that the forms of my invention herewith shown anddescribed are to be taken as preferred examples of the same and thatvarious changes in the shape, size and arrangement of parts may beresorted to without departing from the spirit of my invention or thescope of the subjoined claims.

Having thus described my invention, I claim:

1. A tobacco smoking pipe comprising a bowl, said bowl comprisingseparate upper and lower bowl-sections having engaging ends, saidbowlsections being provided at their engaging ends withcircumferentially extending internal cutaway portions, said cut-awayportions when assembled forming a circumferentially extending internalrecess having its inner side open, a tubular element arranged within thebowl-sections and extending across the open side of thecircumferentially extending recess and having apertures in communicationwith the recess, said tubular element serving to cover the open side ofthe recess to prevent the tobacco from entering the recess and to alsodetachably connect the bowl-sections, and a stem having a passage incommunication with the circumferentially extending recess.

2. A tobacco smoking pipe comprising a bowl including separable upperand lower bowl-sections, the lower bowl-section being provided at itsupper end with an internal frusto-conical wall which flares upwardly,the lower bowl-section having a port in communication with the internalfrusto-conical wall, the upper bowl-section being provided at its lowerend with an internal frusto-conical wall which flares downwardly, theassembled frusto-conical walls forming an annular recess which increasesin width inwardly toward its inner open side, a tubular elementremovably mounted within the upper bow1-section and projecting into thelower bowlsection and being removably mounted therein, the tubularelement extending across the inner open side of the annular chamber andalso serving to detachably connect the bowl-sections, the tubularelement having opening means leading into the annular chamber, and astem secured to the lower bowl-section and having a bore incommunication with said port.

3. A tobacco smoking pipe comprising a bowl including separable upperand lower bowl-sections, the lower bowl-section having internal threadsand provided at its top with an internal frusto-conical wall and alsohaving a stem, said stem having a longitudinal passage which is forkedto provide passages extending upwardly and leading through thefrusto-conical wall, the upper bowl-section being provided at its lowerend with an internal frusto-conical wall to register with the internalfrusto-conical wall of the lower section, said frusto-conical walls whenassembled forming an annular chamber having its inner side open, asleeve removably held within the lower portion of the upper bowl-sectionand projecting below the same and having its lower portionscrew-threaded to enter the lower bowl-section and engaged with thethreads thereof for detachably connecting the upper and lowerbowl-sections, said sleeve extending across the open inner side of theannular chamber and being provided between its ends with an annular setof circumferentially extending apertures leading into the annularchamber.
